Abstract
The aim of this study was to study the effect of zinc oxide-chitosan nanoparticles (Zn-CNPs) on growth performance, plasma constituents, carcass indices, and immune function in rabbit diets. Eighty weaned V-line males rabbits at 5 weeks of age were divided into four dietary groups of control diet; 50 Zn-CNPs; 75 Zn-CNPs;100 Zn-CNPs. Supplementation of Zn-CNPs did not affect final live body weight and average daily weight gain. 100 ppm Zn-CNPs recorded (p < 0.05) higher digestibility of DM, OM, CP, EE, and NFE. Dietary groups of 75 and 100 ppm were higher (p < 0.05) in DCP, TDN (%), and DE (kcal/kg). Zn-CNPs supplementation was higher (p < 0.05) in hot carcass and spleen weights %. The addition of Zn-CNPs in diets promoted dressing%. Significant increases (p < 0.05) in plasma total protein and albumin levels for 75 and 100 Zn-CNPs. Zn-CNPs decreased (p < 0.05) glucose, total cholesterol, LDL concentrations and increased (p < 0.05) plasma zinc levels, IgG, IgM. Plasma HDL level increased (p < 0.05) with 75 and 100 ppm Zn-CNPs. In conclusion, Zn-CNPs supplementations can use safely as a zinc source in rabbits diets without any detrimental effects on growth performance, plasma constituents, and carcass indices. Moreover, 50, 75, and 100 ppm Zn-CNPs enhanced the immune functions.

期刊介绍：
Biotechnology can be defined as any technique that uses living organisms (or parts of organisms like cells, genes, proteins) to make or modify products, to improve plants, animals or microorganisms for a specific use. Animal Biotechnology publishes research on the identification and manipulation of genes and their products, stressing applications in domesticated animals. The journal publishes full-length articles and short research communications, as well as comprehensive reviews. The journal also provides a forum for regulatory or scientific issues related to cell and molecular biology applied to animal biotechnology.
Submissions on the following topics are particularly welcome:
- Applied microbiology, immunogenetics and antibiotic resistance
- Genome engineering and animal models
- Comparative genomics
- Gene editing and CRISPRs
- Reproductive biotechnologies
- Synthetic biology and design of new genomes
